The INDEX in Geneva from April 18 to 21, 2023 – for textile production with a special focus on disposable textiles used in hygiene, medicine, and similar applications is the most important exhibition of its kind and presents investments in the textile production process which meet the latest ecological demands for sustainability, recycling, and reduction in energy consumption.
DiloGroup will present the latest developments in needling technology to draw the visitors’ attention to the latest demands of environmental sustainability in nonwoven production.
The research work of DiloGroup traditionally focuses on production lines for the webforming and needling of staple fibre material.
After years of gradual advancements in intense needling technology, they have succeeded in achieving the industrial scale of “MicroPunch” intense needling technology.
Good abrasion resistance of this intensely needled material allows the production of apparel, artificial leather, battery separators, and filter media as well as medical and hygiene nonwovens.
The production of comfort tissues with a weight range of 30 to approx.
60 g/m² made from fine fibre blends using polyester and viscose has been a domain of the water-entangling technology so far. This product being a typical disposable is in the crossfire regarding sustainability and recyclability. Therefore biodegradable or decomposable fibre material is the target for more environmental sustainability.
In addition, for the evaluation of a web consolidation process, low carbon emission and low energy consumption are important criteria.
The classical needling technology and its qualification for the production of lightweight nonwovens at low cost/kg have been technologically and economically proved in the meantime after many years of research work.
It has become possible by an intense concentration of needles in the board and very fine barbs on these specialty needles which allow an economic mounting and quick exchange due to a new module design.
Compared to water-entangling lines, the “MicroPunch” needling line provides a drastic reduction in energy consumption (electricity and gas).
In view of heavily increased costs for electricity and gas, this reduced consumption has a great impact on the total cost for a kilogram of the finished product in many countries.
